I Application filed November 13, 1905. $erial No. 287,119.

To wZZ whont it may concern:

Be it known that I, GEORGE N. HINCHMAN, a citizen of the United States, residing at Webster Groves, in the county of St. Louis and State of Missouri, haveinvented a cer-. tain new and useful Adding Machine, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to improvements in adding-machines, and more particularly to that class of adding-machines known as the Standard. Adding Machine, and shown and described in the patent to Hopkins, No. In the machine shown in the present application, however, the general operation of the machine is somewhat modified from that shown in the Hopkins patent by the interposition of a set of idle wheels between the intermediate wheels and the adding-wheels and the conse uent avoidance of the reversal of the type-w eels on taking the total. This feature, however, is not claimed in the present application except in combination, as it forms a part of the subject-matter of another application of even date herewith.

One of the principal objects of my invention is to provide a machine of the class named with a repeat device which can be used not only to repeat the numbers written into the machine, but also to re eat the total when transferred from the a ding-wheels to the printing-wheels, and which consequently can be used not only as a repeat device, but also as a subtotal device.

I Another object of my invention is to provide the machine with a character which will be rinted only whenthe total is taken.

till another object of my invention is to Y rovide the machine with improved papereedingmechanism.

Other objects of my invention are to profor various parts of the machine in order to insure the proper operation of the same.

In the accompanying drawings, which illus trate an adding-machine made in accordance with my invention, Figure 1 is a vertical longitudinal section through the front part of I the machine. Fig. 2 is a horizontal section I through the rear part of the machine. Fig. 3 is a detail view showing a part of the connections for operating the repeat mechanism. Fig. 4 is a view rhowing the train of gears for positioning the total-sign. Fig. 5 is a detail view showing a lock for the error-key. Fig. 6 is a side elevation showing the mechanism for controlling the repeat device. Figs. 7 and 8 are enlarged detail views of parts of the mechanism for controlling the repeat device.-

Fig. 9 is a front view of the parts shown in Fig. 6, the frame being shown in section.

Fig. 10 is partly a side view and partly a section of the upper and central portions of the machine. Fig. 11 is a view illustrating work done by the machine. Fig. 12 is a sectional view showing the mechanism for printing one or more zeros before the total-sign. Fig. 13 is a detail view of the error-key and lock therefor. Fig. 14 is a view showing mechanism for controlling the printing-slide when repeating. Fig. 15 is a sectional view through the printing and intermediate gears. Fig. 16 is a side elevation showing the paperfeeding mechanism. Figs. 17, are detail views of portions of the paper-feeding mechanism? Fig, 20 is a top view of the parts shown in Fig. 16. Fi s. 21 and 22 are detail views of portions oi the controlling mechanism for the repeat device, and Figs. 23 to are diagrammatic views showing the various movements of the adding, printin intermediate, and idle ears, to ether with the repeat-gears and t e axially-movable wheel.

Like marks of reference refer to similar parts in the several views of the drawings.

The eneral operation of the machine will first be riefly described. As has been above stated, however, its general operation relates more particularly to the subject-matter of a separate application.

is the base of the machine, and 51 the casing. Carried by the base 50 are side frames 52 and 53, intermediate frames 54 and 55, and rear frames 56 and 57. Carried by the intermediate frames 54 and 55 and the rear frames 56 and 57 are frames 58 and 59, which support the adding-wheels and carrying mechanism.

60 represents the order-keys, and 61 the numoral-keys. These key 5. control the carriage 1s, and 19 i the machine, the parts are in the position and printing wheels in the usual manner.

' the connections through which these operations are performed do not form a part of the present invention, thesame will not be described.

62 is the carriage which controls the axially-mo vable wheel. 63, which transmits the power from the motor 64 to the intermediate wheels 65. The intermediate wheels 65 are mounted upon a shaft 66, carrying a comb 67. The comb 67 is rotated by the operation of the handle and is adapted to come in contact with pins 68 on the said intermediate wheels 65.

69 is a sto for the pin 68.

Each of t e wheels 65 is provided with a centering-pawl 70 which serves to center the type. The intermediate wheels 65 mesh with wheels 71, secured to type-wheels 72. The wheels 71" and'72 are loosely mounted on a shaft 73-.

The carriage 62 is positioned whenthe total is taken by means of order stop-pawls 86, mounted upon a shaft 74 and provided with-dogs 75 and 76, the dogs 76 being adapted tobe thrown into engagement with the teeth of the wheel 71.

Meshing with each of the intermediate wheels 65 is an lidle wheel 77. The idle wheels 77 are loosely mounted upon a shaft 78, which. shaft is operated by the error-key.

' The shaft -78 is provided with a comb 79,

adapted to engage with pins-80 on the said idle wheels 77.

' normally out of engagement therewith, as shown in the drawings. The adding-wheels 81 represents the adding-wheels. These wheels are adapted to bev thrown into engagement with the idle wheels 77, butare 81 are loosely mounted upon a shaft 82'.

The shaft 82 is provided with a longitudi nally-movable comb 83. .This comb 83 is adapted, when moved longitudinally by means of the total-key, .to come in contact with lugs 84 on the wheels 81, but is nor-' stands inlthe position best shownmFig. -1, so

that the wheels 92 are .out of mesh withthe,

85 represents the carryi -bars. w 'The general operation 0 the parts above described will now be given, as the sameis necessary to a proper understanding of my invention.v When a number is written into shown diagrammaticallyin Fig. 23. The axially-movable wheel 63 is operated by the motor and drives the intermediate gears 65, printing-wheels 71, and idle wheels 77 in the direction indicated by the arrows in said figfure.

The adding-Wheels 81, however, are out ofmesh with the idle wheels 77, and conseqiiently are not actuated. If it is now desired'to remove the number from the ma chine on account'of its being erroneous, the

error-key is de ressed, thusdri'ving the idle wheels 77 in t e direction-indicated by the.

This throws the adding-wheels 81 into enthe printing-wheels 71 and idle wheels 77 to their normal position, and transferring the After the numbers have been writteninto the ma- ,chine and it is desired to take the total the total-key is depressed. This also throws the adding-wheels 81 into engagement with the idle wheels 77 In this case, however, the adding-wheels 81 are themselves rotated in the direction indicated by the arrow in Fig. 26," thus transferring the sum through the idle wheels 77 and intermediate wheels 65 to the printing-wheels 71, so that the sum may be printed. In case the subtotal device, is used when the intermediate wheels 65 are rotated to return the parts to their normal position the adding-wheels 81 will remain in mesh with the idlewheels 77 and the parts will be operated in the same manner as illustrated in Fig. 25, heretofore described. If,

however, the subtotal device is not used, the

adding-wheels 81 will remain out of mesh with the idle wheels 77, so that the operation of the parts will be the "same as that indicated in Fig. 2,7','-and the machine will be returned a IOO tov zero. I

Iwill no'w particularly describe the parts Loosely mounted upon the shaft 78 the 'is desired to continue the operation and idle wheels 77 is a frame 90. Loosely jour naled in'this frame is a shaft. 91,;upon

which areloosely mounted the repeat-wheels 92. Secured in-this shaft 91 is a comb 93,

Theframe 90 normally iro printin -wheel gears 71; but said frame'is- Y 'adapte to be moved-by mechanisms hereinafter to be described, so as to throw'the said wheels 92 intoengagement with the wheels 71'; When the frame isin the position sho .inFig. 1, the wheel gzaregrevented. from. y abrace-red.

rotating by ,a blade 8 .7, carrie 88, extending between the side frames 55 and am same has rigidly secured to it at. its left-hand f1 56. In order; to actuate the--' haft". 91, the

end awheel-95, similar to the wheels92. This wheel 95 is'adapted to be thrown into enga ement with-a wheel 96, loosely mounted on t e left-hand end of the shaft 73, upon which the printing-wheels are mounted'. This wheel 96 I in turn meshes with a wheel 97, dly-sei cured to the left-hand end of the s aft '66, upon which the .intermediatelgears -65 are mounted. It will'thus be evident that whenr30 ever wheels 92 into mesh with the printing-wheels 71 and the shaft 66is rotated the shaft 91, upon which the wheels 92- are mounted, will also be rotated. In order to move the frame to brin the wheels 92 into engagement with the w eels 71, the 'saidirame has pivoted to it a link 100. This link is in turn pivoted to one endof a lever 101, the opposite end of which ispivoted to a bent link 102. The link 102 is in turn pivoted to an arm 103, which is rigidly secured. to the end of a rock-shaft 104, supported in a sleeve "105, carried in the side frame 52.

mounted upon the sleeve 105 is an arm 106, having its upper end beveled at 107. This beveled end 107 is adapted to strike against the conical end of a pin 108, carried in a lever 109., which lever 109 is pivoted at 110 to the side frame 52. The lower end of this lever 110 bears upon a link-bar 111, operating a comb 1.12 to lock the order-keys 60 and nu 'rneral-keys 61. Projecting from the arm 106 is a pin 11 1, which cooperates with a pin on an arm 1 16, also loosely mounted upon the sleeve 105. The arm 116 is in the form of a bell-crank lever, one portion of the said arm being in the path of a projection 1 17 npon the plate 118 for operating he intermediate wheelsand the other portion of said arm being attached by a spring 119 to the arm 106. When the rockhaft 104 is operated, it moves the arm 103, which is rigidly secured to it. A finger 120 on said arm comes in. contact with the pin 114, which projects at both sides of the arm 106, and thus moves the said arm, so as to bring its beveled upper end into contact with the pin 108, and thus lock the order and numeral keys. The friction between the arm 106 and the pin 108 will hold the parts in this locked position until the same is released by the operation of the plate 118. When the plate 118 is ope1'ated,its projection 117 will come in contact with the arm 11 6 and through the spring 1 10 will withdraw. the arm 106 out of engagement with the pin. In case, however, the rocleshait 104 is held in position, this movement will only distend the spring 119 without releasing the lock, In Figs. 2, 21, and 22 I have shown the outer end of the rock-shaft 104 provided with an arm 121, arranged in the path of the repeat-key 122. In this construction the repeat-lrey 122 must be pressed in and held in manually until the number in the machine is repeated the proper number of times. Inasmuch, however, as the operator is liable to prematurely release the key 122, I prefer to use the construction shown in Figs. 6, 7, and

In the construction shown in Fi 6, 7, and 9 the arm 121 is replaced by a arm 123,

This arm 123 has an upward extension 12 1,

cooperating with the repeat-key 122, a rearward G2-I1GIDS1OI1 125, and a downward extension 126. The rearward extension is Loosely will be operated,

the frame 90'is moved to bring the 1 adapted to cooperate vith a locking-sector 127 upon the main or handle shaft This sector 127 is so arranged that when the handle-shaft 123 is moved from normal position the said sector will pass directly below the end or the arm 125, and time prevent the repeat-trey 1 from being operated until the handle has returned to its normal position, and the end of the lever is also so arranged that when the triple lever 123 is niovedthe said end will move adjacent to a curved locking-surface 129 on the said sector 127, and thus prevent the handle from being moved until the repeat-key 122, and consequently the lever 1 23 returns to their normal position. The downward extension 126 is provided with a pawl 130, which engages with the segmental 131 to compel the complete movement- 01' the arm 123 in either direction. The arm 123, in place of being rigidly secured to the shalt 104, as is the ease with the arm 121, is loosely mounted. upon said shaft. In order to operate the shaft from the arm 123, the downward projection 126 of said arm is provided with a pin 132, adapted to eontactwith a finger 133 on an arm 13 1, rigidly secured to the shaft 104. This arm 134 is provided with a tooth 135, adapted to be engaged by apawl136. Loosely mounted upon the shaft 104 adjacent to the arm 134 is a ratchet-Wheel 137, and secured to this ratchet wheel is a second ratchet-wheel 138. The ratchet-wheel 137 is provided with only one-half as many teeth as the ratchet-wheel 138 .the portions of the wheel between the teeth on the wheel 137 forming bearing-surfaces 139. The teeth in the wheel 137 are adapted to be engaged by the pawl 136, said pawl being made of suihcieut width ,to engage both with the teeth of the wheel 1.37 and with the tooth on the arm 1.31. A second pawl 140 is provided to engage with the teeth of the wheel 138. The teeth of this wheel 133 are also engaged by a pawl 141, carried by the upward extension 12 1 of the triple arm 123. With this construction it will be evident that when the iarts are in their normal posit-ion, if the repeat-hey 122 is forced in, the triple arrn123 thus preventing movement of the handle-shaft 128. At the same time the pawl 1 11 on the said triple arm will operate the ratchet-wheel 138, moving the same a distance oi one tooth, and at the same 1 the wheel 137 arm with the'tooth 135 on the arm 13a. The arm 134 will thus be locked in its forward position by the pawl 136, and consequently the shaft will be locked in its position, so as to'hold the repeatgears in mesh with theadding-wheel gears 71 and also to hold the arm 106 in engagement with the pin 108, and thus lock the order and numeral keys. When the repeatkey is released, the parts remain in their locked position, as no movement takes place, except in the triple lever 123, which returns to its normal position, so as to allow the handle to be moved. The number may now be repeated the desired number of times. When it is desired to release-the repeat mechanism, the repeat-key 122 is again forced in. Upon this second movement of the re eat-key the arm 123 is again moved, and through the pawl 141-tl1e wheels 138, and 137, areagain moved. By this movement, however, the wheel 137 is brought intosuch position that thedog 136 in place of engaging with one of the teeth upon the said wheel 137 rests upon one of the bearing-surfaces 139 and is thus held. out of engagement'with the tooth135 in its locked position by frlction, as has been.

on the .lever 134, so that the parts'return to their normal position and the repeat-key is thrown out 'of operation. It is to be noted, however, that the locking arm 106 remains previously described, so that the order and numeral keys and 61 are not released until the pull of the handle. Upon the pull of the handle, however, the projection 117 on the. plate 118 strikes the arm 116 and through the tension of the spring 119 withdraws the arm 106. i

In order to lock the ha mers in printing position whenv repeating a number, the link 1.02 is provided with an 11 Wardly-projecting bifurcated engages wit a stud 146 carrie inf'a late 147. This late 147 is se ured to the owe'r side of a coilar' 148, loosely mounted upon a shaft 149. Carried by the collar 148 is a? comb 150. This comb normally stands in the osition showifin Fig. 22. The comb 150 is adapted 'to enga e a projection 151 on the printing-hammer s ide 152, said slide 152 being provided with a comb 153' in the usual manner for operating the printing-hammers ven'ts thejprinting-s 154. Then the comb 150 is thrown-forward to. its normal-position until the re eat mechanism is released. In order to al ow the frota-ry return; of the printing hammer slide 152, '5'5 the lower edges 0 the notches in the printing-hammers which take overthe printing-' hammer shaft 155 are cut away, as shown at 156 in Fig. 22, so that'when'the said slide v makes its rotary return the lower ends of the hammers will be-s' ply forced slightly forward and snapped Flak into position by the hammer-springs, while upon the dOWnWard I movement of the comb 153 the hammers w ll be operated. in the usual manner.

159 is a late loosely mounted on' the-typewheel shafl: 73 and-carryin a sign. 160, used to indicate-the total. T v may be-of any suitable form; but I prefer, to use a lozenge containing the letter S, as shown F ig. 11 of the "drawings. This plate 159 normally stands'inthe position shown in Fig. 4, so as to be out of the'path of the printing-hammer 157, the object of the pin 1'58 being1 to prevent the hammer 157 from driving e pa er and ribbon against the part of the plate elow the printing si 160. A centeringpawl 161 holds the plate 159 in either the print. chine the plate is in the position shown in Fig. 4, the pawl'161 resting-in a notch 162,- while when in the printing position the awl 161 restslin a notch 163. I The rear of the plate 159 is provided with a notch which is engaged by a tooth on a sector'164, loosely mountedu on the intermediate shaft 66.

This sector is provided with a pin 165,-adapted to bethrown against the stop 69, hereinbeforedescribed. The sect0r.164 also engages with a sector 166, loosely mounted upon the'idle-wh'eel shaft 78. i The. sector 166 has an upwardlyrojecting tooth 167, adaptedto be-engagedy the comb 830i the adding-wheel shaft 82. Asthe' shaft 82 is rotated by the total-key 168, whenever the.

said key is 0% ratedthecomb 83 will come in cont'act wit the tooth 1'67 and through the .sectors166 and 164 move the plate 159, so as to bring the printing-sign. 166 in position tov 'be struck'by the'hammer"157 to print the sign, as shown in Fig. 11. .Upon the pull of the handleto return the parts to normal position thejcomb 67 ofthe. intermediate shaft" 66 will engage withthe pin 165-and return the parts tothe position shown in Fig. 4, so that in 'the ordinary operation 'of the machine the sign will not be printed. In connection with the sign-I prefer to print beforethe same one or more zeros when the total-key is depressed and the machine is clear. In Fig. 11

have shownthis in the preferred form, in I which two zeros are printed before the said sign to-showlthat the machine is clear. In

order to accomplish this, theord'er stop-..

pawl's 86 in two less in number than the orders for which the mechanism is arranged,

as shownin Fig. 12, so that when the total- 9 position shown in Figx4or in the positionito.

In the normal'operation of the magaged by a feed-pawl 171, the end of which forms a strap surrounding an eccentric 172, mounted upon a shaft 173, which'is operated by the pull of the handle. Pivoted below the ratchet-wheel 17 0 are two plates 174 and 175. The plate 174 is normally fixed, but can be adjusted by means of a nut 176 on a bolt passing through a slot 177 in the said plate. This plate is provided at its upper end with a flange 178, and the plate 175 is provided with a flange 179, having a shoulder 180. In the normaloperation of the machine these plates stand in the position shown in Fig. 16, the flanges 178 and 179 being some distance apart, and this distance regulates the feed and can be adjusted by means of the nut 176. The plate 175 is held in its normal position. by means of a hook 181, which engages with a shoulder 182 on the said plate. The hook 181 is provided with a pin 183, which engages with a slot 184 in a bell-crank lever 185, loosely mounted on a stud 186. The bell-crank lever 185 is provided with a pin 187, which projects below the feed-pawl.171. The bell-crank lever is connected by a link 188 with a toothed sector 189, loosely mounted upon the shaft 173, hereinbefore described. The pivot connecting the link 188 with the sector 189 is extended to form a stud 190, which passes through a slot- 191 in the error-key bar 192, so that the said sector is operated each time the error-key bar is depressed. when the error-key bar is depressed, the movement of the bell-crank lever 185 raises the feed-pawl 171 out of engagement with the ratchetwheel 170, and at the same time the engagement of the lower edgeof the slot 184 with the pin 183 moves. the hook 181 out of engagement with the shoulder 182, so that a spring 193 moves the plate 175 on its pivot, and thus brings the flanges 178 and 179 into contact, so that upon the next movement of the handle the feed-pawl 171 cannot fall into engagement with the ratchet-wheel 170, but engages with the shoulder 180 in the flange 17 9, and thus draws the plate 175 back into normal position, in which it is held by the hook 181, so that upon the succeeding movement of thehandle the paper is fed in the normal manner.

In order to prevent'the depression of the error-key when the handle is out of its normal position and to also prevent the movement of the handle when the error-key is out of its normal position, the shaft 173, which is operated by the handle, is provided with a sector 195, and the error-key bar 192 is provided with a pin 196, these parts being arranged as best shown in Fig. 7. It will be evident that whenever the shaft 73 is moved by the operation of the handle the sector 195 will move below the pin 196, and thus efiectually prevent the depression of the error-key bar, and that when the error-key bar is depressed the movement of the pin 196 behind the sector will prevent the movement of the handle. In Fig. 5 I have also shown an additional lock for the error-key bar. 197 is an arm loosely mounted'on the handle-shaft 128 and operated by the depression of the error-key. This arm is adapted to be engaged by the overturned end 198 of a bell-crank lever 199. The opposite end of this bell-crank lever 199 is bifurcated and engages with a pin 200 upon a cradle 201, which is operated by the depression -of the order-keys 60. In conseuence of this construction whenever one of t e order-keys is depressed to swing the cradle 201 upon the shaft 128 the bell-crank lever 199 is..rocked, so as to move its overturned end 198 over the arm 197, and thus prevent the depression of the error-key.

I will now particularly describe the complete operation of the-machine in so far as the same is affected by my improvements.

The number is written into the machine by manipulating the order and numeral keys 60 and 61 in the usual manner. Now if it is desired to repeat the number before operating the handle the repeat-key 122 is forced inwardly. The action of the key 122 swings the triple arm 123 on its pivot, thus bringing its rear extension 125 in the path of the sector 127, so that the handle cannot be oper' ated. This movement of the lever 123 also is communicated through the pawl '141to the ratchet-wheel 138. As the wheels 137 and 138 are rigidly secured together the wheel 137 will also be rotated. The pin 132 in the arm 126 will come in contact with the finger 133, and thus move the lever 134, which is rigidly secured to the shaft 104. The shaft 104 will 'thus be operated to move the arm 103 and at the same time will be locked in this position by the engagement of the pawl 136 with the tooth135 on the arm 134. When the repeatkey 122 has completed its movement, the pawl 130 and segmental rack 131 will allow its return to normal position, so that the bandle may be operated. The movement of the arm 103 will be communicated through the link 1-02, lever 101, and link 100 to the frame 90, so that the said frame will be drawn down to bring the repeat-wheels 92 into engagement with the type-gears 71. At the same time the link 102, through its upward bifurcated portion 145, will rock the sleeve 148 on its shaft 149, so as to bring the comb 150 into engagement with the pro'ecflon 151 on the printing-slide 152, and t us look the said 1 to it the gear 97,the movement of the said shaft will be communicated through the saidgear and the gears 96 and 95 to the shaft 91 of the repeat-wheels. The comb 93 in said shaft will thus be moved away from the pins 94 and at the same time as the wheels 92 are in engagement with the type-gears 71 the wheels 92, corresponding to any of the typewheels which have been operated in printing the number, will be moved, so that the pins in said wheels will follow the comb 93 one or more teeth, acoordin to the number written in on the type-whee. Upon the return of the shaft 66 to its normal position the shaft .91 Will again be rotated by means of the train of gears 95, 96, and 97 and be returned to its normal position, the 'comb 93 striking the pins'94 of any wheels which have been moved,

and thus again setting up the number in the printing-wheels. This operation will be reeated as many times as the handle is drawn orward. When the handle has been drawn forward as many times as desired, less one, the error-key is again'forced in. This second movement of the repeat-key moves the wheel 138 a second notch, thus bringing one of the bearing-faces 139 of the wheel 137 into engagement with the pawl 136, and so holding the pawl out of engagement with the tooth 135 on the arm 134,.so that upon the release of the repeat-key the said arm 134 can swing back into normal position, thus releasin the repeat mechanism and-allowing the wheels 92 to move out of engagement with the wheels 71. The handle can now be drawn forward another time to complete the desired number of repeats. One advantage of my construction, however, is that in case the operator should pull the handle as many times as required before releasing the repeat mechanism the last repeat setup in the machine can be thrown out by means of the error-key 192, as there is nothin in the repeat mechanism to prevent the or inary operation of the error-key. The total is taken on the machine in the usual manner by depressing the total-key 168. It will be evident that the repeat mechanism above descn'bedcan be used in repeating the total thus obtained, as the parts after depressing the total-key are in the same position as if the number had been written into the machine by means of the keys. It is therefore only necessary after depressing the total-key to operate the repeat-key and the total can be repeated asmany times 'as desired. 4 This operation is useful in varlous ways. One advantage of thus being able to repeatthe total is that the repeat-key may be used in place of a subtotalkey. 'After taking the total the repeat-key the comb 83, and the movement of said comb is communicated through the train of gears 166 and 164 to the plate 159, carrying the printing-sign 160, so as to throw said sign into position to print,-and thus indicate that the total has been taken. This is especially useful in long calculations where the subtotal is taken a number of times, as the totals can thus be readily distinguished from the individual numbers. .It is also useful in connection with the two ciphers, as shown 111 Fi 11, to indicate that the machine is clear be ore and after doing a sum in addition.
